Quoted from markmon:They are very hard to stretch so it takes a bit of effort to put them on. They're tight so they don't seem like they will come off easily.
Hard to stretch is an accurate statement.
I couldn't get these on before I "worked" them.
I had to take both hands and stretch the shit out of these. Then, and only then did they go on...and they were still a son of a bitch to get on.
I notice a lot of stick compared to rubber rings. I'm also getting air balls on Metallica and AC/DC on one timers.
I'm hoping these will calm down with use. Other than that, I'm happy with them.
